DP A1S is a Norwegian legend. One of the best amplifiers of the world. Distortion level is at par with or lower than Halcro DM 88. Sounds increadibly clean an dynamic. A wire with gain. More live feeling than almost any amplifer. Drives any loudspeaker and has a damping factor of 1000 @ DC - 20kHz/8?.

Unfortunately the amp is discontinued after Electrocompaniet bought the brand from the original constructor. Very rare to come by in the classifieds.
